everything about the spinycheek scorpionfish
who is the spinycheek scorpionfish
The spinycheek scorpionfish belongs to the family Scorpaenidae and has its head armed with spines, including on the cheek. It reaches 40 cm. It lives in the western Atlantic, on bottoms of 45 to 230 m, from New Jersey to southern Florida and the Gulf of Mexico. In Latin America it occurs in Mexico and Cuba. It is taken commercially. Like other scorpionfish, it is a bottom predator that stays still and waits for prey to pass. The fin spines have thick glandular tissue along the rear edge, which is believed to be venomous, so they deserve care.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the spinycheek scorpionfish; in the meantime, see the similar species.
identification
Scorpionfish with a spiny head, with spines also on the cheek, which gives the species its name. The fins have firm spines, and the rear edge of them has thick glandular tissue. It resembles other scorpionfish of the family, such as the baetinha (Scorpaena plumieri), but lives on much deeper bottoms, 45 to 230 m, while the baetinha is found between 1 and 70 m.
where found
In Latin America it occurs in Mexico and Cuba, on deep bottoms of the Gulf of Mexico and the Caribbean.
Habitat: Bottoms of 45 to 230 m, well below shallow reefs.
rules for the spinycheek scorpionfish
Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
We found no species-specific rule beyond the region's general rules.
catch and release
catch and release Releasing the fish alive, quickly and with a wet hand. During a closed season it isn't always allowed: what the regulation says applies.
The spines have a gland believed to be venomous, so hold the fish with a thick cloth. Because it comes from deep water, it suffers the pressure change when brought up (barotrauma). Release it carefully, preferably while it is still in the water.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01288, b = 3.02; FishBase (relação peso-comprimento bayesiana, estimativa)). It's an average: a fat or lean fish can vary by 10% to 20%.

Essential profile: size, length-weight, depth, countries and conservation come from FishBase and the cited regulations, and the texts were written from those sources. Season, time of day, sensitivities, technique and baits and lures are not included yet, because we did not find a good source for this species.

where each number comes from
The weather comes from three independent global models, cross-checked hour by hour: when they agree, confidence goes up; when they diverge, the band between them shows on the chart. Beyond 16 days, we use the GEFS ensemble of 31 simulations: if 20 of the 31 predict rain, the chance of rain is 65%. Sun and moon are calculated astronomically, with no uncertainty.
The index adds up, weighted for each species: time of day (species curve anchored to real sunrise and sunset), moon (transits, rise and set, phase), pressure (3 h trend and 24 h swing), water temperature (in rivers, estimated from air temperature; at sea, estimated by an ocean model), wind, rain, clouds, tide and the month in the species' cycle.

how accurate the forecast is
Accuracy measured in the reference project (4 regions, 93 days, forecast vs. observed): maximum temperature is off by 0.6 °C on average the next day and 1.7 °C at 7 days; rain of 5 mm or more is detected 76% of the time the next day and 57% at 7 days. Detection isn't everything: the false alarm rate isn't published here yet, and 93 days in 4 regions is still a small sample. We now also measure every day, at the app's destinations:
